Abstract:
Systems and methods are described for providing coaching, training, or equipment specification information to individual golfers based on data generated during their individual golf swings. Additionally, data hubs are described that provide information and services to individuals based on data collected for a community of multiple golfers. Such community data hub systems and methods may provide one or more of the following: (a) storage of scoring data, swing data, ball flight data, and/or equipment data for multiple golfers; (b) at least some level of individual access to the stored data for the community; and/or (c) electronic interaction between golfers within the community.
Abstract:
A sports helmet notification system to be carried by a helmet has a microcontroller in connection with an accelerometer that measures acceleration in three mutually orthogonal directions, a memory device and a notification device. The microcontroller has a predetermined logging setpoint and a predetermined notification setpoint. The microcontroller is programmed with instructions to record an event in the memory device upon receiving acceleration data from the accelerometer that exceeds the logging setpoint and to activate the notification device upon receiving acceleration data from the accelerometer that exceeds the notification setpoint.
Abstract:
An individual tension meter (1) for measuring tension in a racquet string (9), includes a graspable body (10) and a stress member (2) for stressing the string (9) that are movable relative to each other by pivoting, elastically deformable return elements (3) configured to urge the graspable body (10) and the stress member (2) relative to each other back into a neutral angular position, measurement elements for measuring a magnitude representative of the relative pivoting between the graspable body (10) and the stress member (2), and computation elements for computing the tension of the string as a function of the measured magnitude. The graspable body (10) and the stress member (2) have a first possibility of pivoting relative to each other in a first direction and a second possibility of pivoting relative to each other in a second direction opposite from the first direction.
Abstract:
In order to determine a position of a mobile object relative to a surface within a movement range that comprises a ground which the surface intersects along a line of intersection, a magnetic field of a first elongate magnetic field-generating object which is located at a first distance from the line of intersection is measured, and a magnetic field of a second elongate magnetic field-generating object that is located in or on the ground, at a second distance on another side of the line of intersection, is measured. Based on a comparison between the measured magnetic fields, it is determined whether the mobile object is located in front of or behind the surface. A generator that triggers the magnetic field-generating objects in a multiplex mode is provided for distinguishing which magnetic field-generating object generates which magnetic field. The magnetic field-generating objects can comprise forward conductors of a conductor loop, oppositely wound coils, or forward/return conductor combinations having a magnetically shielded return conductor.

A device for generating a magnetic field in a goal area with at least two coils arranged in parallel to a goal area defined and bounded by a goal, wherein a first coil is attached in an area behind the goal and a second coil is attached closer to the goal than the first coil or identical to the goal, wherein the first coil and the second coil respectively have a coil impedance, wherein the coil impedance of the second coil is set so that a magnetic field of the second coil generated due to a magnetic field of the first coil reduces the magnetic field of the first coil at a location within the second coil by at least 20%.
Abstract:
For the realization of the industrial project above mentioned, look at all the phases for creating the electronic bladder. Ten different versions have been invented to lodge the microsensors, up to the enough quantity, or the pressure system itself. Pictures (1), (2), (3), (4), (5), (6), (7), (8), show how the electronic sensors of survey and transmission can be lodged. Pictures (9), (10), show the cobweb that can be created in the center of the bladder to lodge the pressure microsensors, the metallic surveying microsensors, or the infrared rays ones. Picture (11) shows the lodging of the electronic surveying system under the grass cover, that immediately transmits any signal noticed to the chronometer or bracelet in endowment to the central referee or to his collaborators. Always in the figure (11) the signs show as: (A) the electronic football is going to enter the goal line, (B) half of the electronic football over the goal line, (C) the electronic football has (B) gone beyond the goal line. The referee immediately receives communication of the happened goal.
Abstract:
A golf swing timing training aid for perfecting a golf swing that provides both an audible and vibrational feedback indicator when the apogee of a back swing has been reached, when the swing accelerates downward, and when the apogee of the follow-through swing has been reached. The golf swing training aid is unobtrusive and inconspicuous, and is capable of being hidden within a golf glove.
Abstract:
A sports training aid has a pair of foot sensors, insertable in a pair of shoes, which generate measurement signals indicative of weight applied to each of the foot sensors. The training aid compares the measurement signals with a specified range of values and produces audible sounds indicative of the relationship between those measurement signals and the specified range of values, thereby providing the training aid's user with immediate audible feedback regarding weight shifts. A grip sensing version of the sports training aid uses a grip pressure sensor which generates a measurement signal indicative of grip pressure applied to the handle of a swingable object, such as a golf club or baseball bat. When the user's grip pressure falls outside specified threshold values, audible tones are generated. In both versions, the user receives the audible feedback signals via a headset worn while using the sports training aid. A spinal tilt version is used to train a person to maintain proper spinal tilt during a sports motion, and a shoulder rotation is used to train a person to achieve a proper degree of shoulder rotation during a sports motion such as the golf backswing. In each version, the sensor(s) include a transmitter which transmits the measurement signals at a predefined frequency. The transmitted measurement signals are received by a comparator which compares the received signals with the specified range of values. As a result, the sensors and comparator need not be physically connected.
